Specific Meanings (specific + meaning)
Selected AbstractsA review of the terms agglomerate and aggregate with a recommendation for nomenclature used in powder and particle characterizationJOURNAL OF PHARMACEUTICAL SCIENCES, Issue 10 2002Gary Nichols Abstract The terms "agglomerate" and "aggregate" are widely used by powder technologists to describe assemblages of particles that are found in dry powders and powders in liquid suspensions. Each term has a specific meaning but, unfortunately, they are frequently interchanged at will and this has resulted in universal confusion. This confusion is perpetuated by conflicting definitions in national and international standards and this presents problems when describing powder properties or communicating results in reports and research papers. This paper reviews the current status of the definitions, with particular emphasis on their use in the pharmaceutical industry. It is proposed that just one term, agglomerate, should be used to describe an assemblage of particles in a powder and that the term aggregate should be confined to pre-nucleation structures. © 2002 Wiley-Liss Inc. and the American Pharmaceutical Association J Pharm Sci 91:2103,2109, 2002 [source] Cultural Meanings and Cultural Structures in Historical ExplanationHISTORY AND THEORY, Issue 3 2000John R. Hall One way to recast the problem of cultural explanation in historical inquiry is to distinguish two conceptualizations involving culture: (1) cultural meanings as contents of signification (however theorized) that inform meaningful courses of action in historically unfolding circumstances; and (2) cultural structures as institutionalized patterns of social life that may be elaborated in more than one concrete construction of meaning. This distinction helps to suggest how explanation can operate in accounting for cultural processes of meaning-formation, as well as in other ways that transcend specific meanings, yet are nonetheless cultural. Examples of historical explanation involving each construct are offered, and their potential examined. [source] Foucault, Rape, and the Construction of the Feminine BodyHYPATIA, Issue 1 2000ANN J. CAHILL In 1977, Michel Foucault suggested that legal approaches to rape define it as merely an act of violence, not of sexuality, and therefore not distinct from other types of assaults. I argue that rape can not be considered merely an act of violence because it is instrumental in the construction of the distinctly feminine body. Insofar as the threat of rape is ineluctably, although not determinately, associated with the development of feminine bodily comportment, rape itself holds a host of bodily and sexually specific meanings. [source] Discrete thermodynamics of chemical equilibria and classical limit in thermodynamic simulationISRAEL JOURNAL OF CHEMISTRY, Issue 3-4 2007Boris Zilbergleyt This article sets forth comprehensive basic concepts of the discrete thermodynamics of chemical equilibrium as balance between internal and external thermodynamic forces. Conditions of chemical equilibrium in the open chemical system are obtained in the form of a logistic map, containing only one new parameter that defines the chemical system's resistance to external impact and its deviation from thermodynamic equilibrium. Solutions to the basic map are bifurcation diagrams that have quite traditional shape but the diagram areas feature specific meanings for chemical systems and constitute the system's domain of states. The article is focused on two such areas: the area of "true" thermodynamic equilibrium and the area of open chemical equilibrium. The border between them represents the classical limit, a transition point between the classical and newly formulated equilibrium conditions. This limit also separates regions of the system ideality, typical for isolated classical systems, and non-ideality due to the limitations imposed on the open system from outside. Numerical examples illustrating the difference between results of classical and discrete thermodynamic simulation methods are presented. The article offers an analytical formula to find the classical limit, compares analytical results with these obtained by simulation, and shows the classical limit dependence upon the chemical reaction stoichiometry and robustness.
